Testing the 3D printers
Overview

Objectives
1.Test and tune the 3D printers that you have in the lab;
Summary
At the SantaChiara Lab in Siena we have 3 FDM printers and one STL printer. This page collects the tests that we made with the following machines:
1.
Ultimaker2: 3D FDM Printer;
2.
Luzbot TAZ: 3D FDM printer;
3.
Flashforge Dreamer: 3D FDM printer;
4.
DWS Xfab: 3D sthereolithographic Printer;
Introduction
The testing of the machines was conducted on the following parameters:
Size: the object is 4x50x50mm (baseplate)
Hole size: 3 holes (3/4/5mm)
Nut size: M4 Nut should fit perfectly
Fine details: pyramide, cone, all numbers
Rounded print: wave, half sphere
Minimum distance between walls: 0.1/0.2/0.3/0.4/0.5mm
overhang: 25°/30°/35°/40°/45°
bridge print: 2/3/4/5/6/7/8/9mm
surface: all the flat parts
In order to check all these things, we used
this STL file.
Ultimaker 2: Cura settings
Luzbot TAZ: Cura settings
Flashforge Dreamer: Flashprint settings
Conclusions
In our test we did push all the three machines to print at their best quality and it turned out that the Flashforge has the best resolution and capability to print overhangs. Both the Luzbot and the Ultimaker delivered insufficient results.
